' 'wArnn PLANE.

Application filed February 21, 1928. Serial No. 256,020.

This invention relates to a seaplane, the general object of the invention being topro vide a pair of frames, each having radiating 7 arms with, watertight pontoons having their ends connected with the arms and a car having its ends rotatably supported at thecenters of the frames so that the car will remain in an upright position if the frames and the pontoons rollunder the action of the waves. I

Another object of the invention is to so arrange the pontoons that but two of them will rest on the water at a time, thus reducing the resistance oifered by the water to,

the passage of the plane and enabling the. plane to travel at great speedwith the minimum amount of power. 7

A still further ob'ect of the invention is to. so arrange theengine and the cargo space that the'.weigl1t o'fthe cargo and of the engine will help to hold the car inan up right position during the rolling motion of the frames and the pontoons.

This invention also consists in certain other features of. construction and in the combination and arrangement of the several parts, to be hereinafter fully described, il-

at each end thereof and a rudder in the rear. Figure 3 is an end view showing the plane provided with three pontoons.

Figure 4 is a similar view, but showing the plane provided with four pontoons.

Figure 8 is an elevation, partly in section,

showing the plane provided with a'front propeller and a rudder at the rear; 7

in these views, A indicates the'end frames to, which the pontoons B are connected. Each end frame comprises a central bearing member 1 and the radiating arms 2, the cyling, ,members.

- CillgO- space *inder-lilte pontoons' B having their ends connected with the ends of these arms. As shown, the ends of the ,pontoons are rounded so that 'theycan pass through the water with the. least resistance; The car G is formed with trunnions 3 at its ends and thesetrunnions are rotatably supported in the bearing members, anti-friction bearings 4 being placed between the trunnions and the bear- Thus the carv is rotatably supported by the pontoons and the frames and the parts are so arranged that but two .of the pontoons will. reston the water at a time andthese-pontoons will support the car above the water. The engine Sand the the car so that the weight of the cargo and of the engine willhelp maintain'the car upright during the rolling motion of the frames and pontoons under the-action of the waves. l. may use three pontoons arranged as shown in Figure 3, or four pontoons may be used, as shown in Figure 1.

The device is driven through means of an air propeller6 placed at the front end of the device and if desired, a second propeller 7 may beplaced at the rear of the device,

as shown in Figure 2, Figure 1 showing but'a single propeller placed at the front end of the plane. 'The propeller shaft 8 passes through the trunnion and is geared to the shaft 9 driven from the engine-by the gears 10. VVhen two propellers are used, a shaft 8"eXtends entirely through. the car, with a" propeller on each end thereof and this shaft is geared-to the engine shaft, as shown in Figure 2.

Figures 1 and 5 rudder is operated from the steering wheel 12 throughmeans of the drum 13, the cables show the rudder 11 a-r-- ranged at the front endof thecraft and this 6 are arranged in the. bottom of 14- connected with the drum and passing over suitable guiding means and connected wlth an arm 15 fastened to the inner end of a shaft 16 which passes through thefront trunnion and is connected with the vertically arranged rudder shaft 17 by the gears 18.

Figures 2 and Sshow the rudder arranged at the rear of the craft and in this case, the cables'l l extend to the rear of the car and are fastened to the arm 15 of the shaft 16 which passes through the rear trunnion and is geared to the shaft of therudder 11'. t

Figure 5 shows how the car may be arranged to form the pilot'house and, chart room. 19, the quarters for the passengers 20 and the sleeping quarters 21 for the crew and passengers, but it Wlll, of course, be under stood that the interior part of the car may be,

arranged to suit the purposes for which the craft is used. This figure also shows the car provided with the air intake 22 and the siphon vent 23. The numeral 24 indicates the cargo hatch.

From the foregoing it will be seen that I have provided a craft which can travel through the water with but little resistance from the water so that it can travel at great speed with the minimum amount of power, and that the car will remain upright at all times even though the pontoons and their frames are rolling under the action of the waves. The craft is also practically unsinkable, due to the watertight ontoons.

The pontoons are provided with the braces 25 which are connected with the bearing members.

It is thought from the foregoingdescription that the advantages and novel features of my invention will be readily apparent.

It is to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claims.

hat I claim is 1. A watercraft comprising a pair 01 end frames )ontoons connected with the outer portions of the frames, with the p ontoons arranged in a circle and a car having trunnlons at its ends whlch are rotatably supported in the centers of the frames. I

2. A Watercraft com XlSlIl a a )air of end s l frames ontoons connected with the outer portions of the frames, with the pontoons arranged in a circle, a car having trunnions at its ends WhlCll'lIG-YOtltttblY supported in the centers 01" the frames an'd'an air propeller for driving the craft.

3. A Watercraft comprising a pair of end frames each consisting of a centrally arranged bearing member and radiating arms, cylindrical-like pontoons connecting the frames together and having their ends con-' nected with the outer ends of the arms, a car having trunnions at its ends which pass through the bearing members, an air propeller at the outer end of one trunnion, a rotor in the car for driving the propeller, a rudder supported from one of the trunnions and means for operating the rudder from within the car. 7

In testimony whereof I aflix my signature.
